Unit joint angular velocities. which define the IHA direction. Pure supination occurs when all components fall within the grey areas. One SD bars are provided every 5°, except for the subtalar joint, where each subject is represented by a unique line color (due to the rapidly changing direction of the subtalar IHA, creating a subject average did not represent the data well).
